PIEZOELEKTRISCHER ANTRIEB BETRIEBSFÄHIG IN ELEKTROLYTISCHER FLÜSSIGKEIT |
摘要 |
A piezo-electric actuator operable in a fluid. The actuator has a piezo-electric element having one or more layers of piezo-electric material and electrodes adjacent to the piezo-electric material, the electrodes being coupled to electrical leads. A conductive layer surrounds the piezo-electric element, serving as a Faraday cage for shielding the fluid from effects due to electric fields within the conductive layer. A seal substantially impermeable to the fluid surrounds the piezo-electric element. |
